You can enable or disable the Intrusion Prevention System (IPS) for all Services on the Barracuda Load Balancer from the BASIC > Intrusion Prevention page. This page displays a list of all of the Services and whether IPS is enabled for each one.
By default, IPS is disabled for a newly created Service. To enable IPS for an individual Service, edit the Service and select the IPS option on the Service Detail page.

See Understanding Intrusion Prevention for an overview of IPS and how the Energize Updates feature works.
